Answer:
13 Units-correct on edge
Step-by-step explanation:
The length of line segment VT in which SU and VT are chords that intersect at point R is 13 units
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
Using the intersecting chord theorem:
VR * RT = SR * RU
(x + 1)(x + 4) = x(x + 6)
x² + 6x = x² + 5x + 4
x = 4
VT = VR + RT = x + 1 + (x + 4) = 4 + 1 + 4 + 4 = 13 units
The length of line segment VT in which SU and VT are chords that intersect at point R is 13 units

Answer:
Option A: f(x) = 4 * 2^x
Step-by-step explanation:
4 because it is the y intercept.
2 because if you see point (1,8), yousee the 8 = 4 * a^1 where a = 2
If you need more explanation, please comment below.
Thank you!!
Answer:
A. [tex]f(x)=4\cdot (2)^x[/tex]
Step-by-step explanation:
We have been given graph of a function. We are asked to write the function formula from given graph.
We can see that our given function is an exponential function, so it will be in form [tex]y=a\cdot b^x[/tex], where,
a = Initial value or y-intercept,
b = Growth rate.
We can see that y-intercept is 4.
Now, we will solve for b using the point (1,8) as:
[tex]8=4\cdot b^1[/tex]
[tex]8=4\cdot b[/tex]
[tex]\frac{8}{4}=\frac{4\cdot b}{4}[/tex]
[tex]2=b[/tex]
Therefore, our required function would be [tex]f(x)=4\cdot (2)^x[/tex] and option A is the correct choice.

How to find the rate of change of a linear equation?Suppose that the considered linear equation is of the form [tex]y = mx + c[/tex]
Then, when we change x by 1 unit, then:
[tex]y + \delta y = m(x + 1) + c\\mx + c + \delta y = mx + c + m\\\delta y = m[/tex]
where [tex]\delta y[/tex] shows the change in y as x changes by 1 unit.
We found that this change is the value of 'm'.
It is called slope of the line this equation represents (each linear equation represents a line).
Finding rate of each item:
Case 1: y = 3x - 11The rate is 3 units increment in y per unit increment in x. In short, the rate is 3 unit / unit increment in x
Case 2:Since graph of a straight line is given, we can find its slope which would represent its rate.
Consider x = 0, for which y = 0 is given in graph.
Now change x by 1 unit, so x becomes x = 1
At x =1 , y = 2
So we see that as x changes by 1 unit, y goes from 0 to 2 (change of 2 units).
Hence, the rate is 2 units increment in y per unit increment in x. In short, the rate is 2 unit / unit increment in x
Thus, the rate of change of item I is greater than the rate of change of item II. (Option A)

Graph AABC with vertices AC-3, 4), B(-1,2), and C(-2,0) and its image after a 270° rotation about the origin.
Answer:
Here's what I get.
Step-by-step explanation:
The formula for rotation of a point (x,y) by an angle θ about the origin is
x' = xcosθ - ysinθ
y' = ycosθ + xsinθ
If θ = 270°, sinθ = -1 and cosθ = 0, and the formula becomes
x' = y
y' = -x
A: (-3,4) ⟶ (4,3)
B: (-1,2) ⟶ (2,1)
C: (-2,0) ⟶ (0,2)
The vertices of A'B'C' are (4,3), (2, 1), and (0, 2).
The Figure below shows the triangle before and after the rotation.

Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
First, expand.

Which of the graphs above is the graph of the equation below?
y = 13 – 632 + 111 - 6 = (1 - 3)(1 – 2)(1 - 1)
Shown below
Step-by-step explanation:To solve this problem, we need to analyze the leading coefficient and the roots of the polynomial function:
[tex]f(x)=x^3-6x^2+11x-6[/tex]
Recall that a polynomial function can be represented by:
[tex]f(x)=a_{n}(x)+ \ldots +a_{1}x+a_{0}[/tex]
So the leading coefficient is [tex]a_{n}[/tex]. In our problem, this coefficient is [tex]a_{n}=1[/tex]
Since [tex]n[/tex] is odd and the leading coefficient [tex]a_{n}>0[/tex], then the graph must falls to the left and rise to the right. Also, the roots are [tex]x_{1}=1 \ x_{2}=2 \ and \ x_{3}=3[/tex]. So the only graph that matches this is the fourth one as indicated below.

Emily went to a local shop to purchase some round rugs. Each rug has a radius of 3 feet. She is
trying to cover as much of the floor of her 18 foot by 20 foot living room as possible without
any overlap of the rugs. How much of the bare floor will be visible around the rugs?
A. 20.76 square feet
B. 254.47 square feet
C. 9 square feet
D. 105.5 square feet
Answer:
D. 105.5 square feet
Step-by-step explanation:
Given:
The rug has a radius of 3 feet.
The floor dimensions are 18 feet by 20 feet.
Now we have to find the area of the rug using area of the circle formula and also we need to find the area of the floor which is in rectangle shape.
Area of a circle = [tex]\pi r^2[/tex]
r = 3 feet and the value of [tex]\pi = 3.14[/tex]
Now plug in the given values in the above formula, we get
Area of a rug = 3.14*3*3
Area of a each rug is 28.27 square feet.
Now let's find the area of the floor.
Area of the floor = length * width
Here length = 18 feet and width = 20
The area of the floor = 18*20
= 360 square feet
Now we have to find how many rugs needed to cover the floor without overlap.
Here the radius of the rug = 3 feet
The diameter of the rug = 2*radius = 2*3 = 6 feet
So one rug covers 6 feet by length and width.
Therefore, 18/6 = 3
The width is 20 feet
20/6 = 3, we have to take the whole number part only.
So Emily needs only 3*3 = 9 rugs.
The area of the 9 rugs = 9*28.27 = 254.43
To find the bare floor will be visible around the rugs, we need to subtract the area of the 9 rugs from the floor area
Bare floor = 360 - 254.43
Bare floor = 105.5 square feet.

Answer:
x + 3x + 5 = 101
Step-by-step explanation:
Consider your problem and think of an equation of each person. We know that Aylen has a certain amount of money, which will be x. Rich though has 5 more than 3 times Aylen.
Aylen: x amount of money
Rich: 5 more than 3 times the amount of money of Aylen.
5 more indicates addition, 3 times indicates multiplication
So then:
Rich: 5 + 3x (where x is the amount of money of Aylen)
Now both of them have $101 together, in other words, if you add up their money they would have $101. So we add their equations:
x + 5 + 3x = 101
Because the operation is addition, we can switch their places and the result will not change so the answer would be:
x + 3x + 5 = 101

If x varies directly with y and x = 6 when y = 15, find x when y= 20.
Answer:
8
Step-by-step explanation:
Varies directly think y=kx
Varies indirectly think y=k/x
We have first option so y=kx
x=6 and y=15 means we have 15=k(6)
So k=15/6 or reducing gives=5/2
So we just found our constant of proportionality, this number never changes. It stays the same no matter what x or y they give you...
So the equation is y=5/2 *x
Now what is x if y=20
Plug in 20=5/2 *x
So x=20*2/5=40/5=8
